Assuch, the therapeutic effect can be a decrease in the severity ofsymptoms associated with the disorder and/or inhibition (partial orcomplete) of progression of the disorder, or improved treatment,healing, prevention or elimination of a disorder, or side-effects. Theamount needed to elicit the therapeutic response can be determined basedon the age, health, size and sex of the subject. Optimal amounts canalso be determined based on monitoring of the subject's response totreatment.

As used herein, the terms “treat,” “treated,” or “treating” mean boththerapeutic treatment and prophylactic measures wherein the object is toslow down (lessen) an undesired physiological condition, disorder ordisease, or obtain beneficial or desired clinical results. Beneficial ordesired clinical results include, but are not limited to, alleviation ofsymptoms; diminishment of extent of condition, disorder or disease;stabilized (i.e., not worsening) state of condition, disorder ordisease; delay in onset or slowing of condition, disorder or diseaseprogression; amelioration of the condition, disorder or disease state orremission (whether partial or total), whether detectable orundetectable; an amelioration of at least one measurable physicalparameter, not necessarily discernible by the patient; or enhancement orimprovement of condition, disorder or disease. Treatment includeseliciting a clinically significant response without excessive levels ofside effects. Treatment also includes prolonging survival as compared toexpected survival if not receiving treatment. Thus, “treatment of pain”or “treating pain” means an activity that alleviates or ameliorates anyof the primary phenomena or secondary symptoms associated with the painor other condition described herein.

As used herein, the term “ureido” means —NHC(═O)—NH₂.

At various places in the present specification, substituents ofcompounds may be disclosed in groups or in ranges. It is specificallyintended that embodiments include each and every individualsubcombination of the members of such groups and ranges. For example,the term “C₁₋₆alkyl” is specifically intended to individually disclosemethyl, ethyl, propyl, C₄alkyl, C₅alkyl, and C₆alkyl.

For compounds in which a variable appears more than once, each variablecan be a different moiety selected from the Markush group defining thevariable. For example, where a structure is described having two Rgroups that are simultaneously present on the same compound, the two Rgroups can represent different moieties selected from the Markush groupsdefined for R. In another example, when an optionally multiplesubstituent is designated in the form, for example,

then it is understood that substituent R can occur s number of times onthe ring, and R can be a different moiety at each occurrence. In theabove example, where the variable T¹ is defined to include hydrogens,such as when T¹ is CH₂, NH, etc., any H can be replaced with asubstituent.

It is further appreciated that certain features described herein, whichare, for clarity, described in the context of separate embodiments, canalso be provided in combination in a single embodiment.

Conversely, various features which are, for brevity, described in thecontext of a single embodiment, can also be provided separately or inany suitable subcombination.

It is understood that the present embodiments encompasses the use, whereapplicable, of stereoisomers, diastereomers and optical stereoisomers ofthe compounds, as well as mixtures thereof. Additionally, it isunderstood that stereoisomers, diastereomers, and optical stereoisomersof the compounds, and mixtures thereof, are within the scope of theembodiments. By way of non-limiting example, the mixture may be aracemate or the mixture may comprise unequal proportions of oneparticular stereoisomer over the other. Additionally, the compounds canbe provided as a substantially pure stereoisomers, diastereomers andoptical stereoisomers (such as epimers).

The compounds described herein can be asymmetric (e.g., having one ormore stereocenters). All stereoisomers, such as enantiomers anddiastereomers, are intended to be included within the scope of theembodiments unless otherwise indicated. Compounds that containasymmetrically substituted carbon atoms can be isolated in opticallyactive or racemic forms. Methods of preparation of optically activeforms from optically active starting materials are known in the art,such as by resolution of racemic mixtures or by stereoselectivesynthesis. Many geometric isomers of olefins, C═N double bonds, and thelike can also be present in the compounds described herein, and all suchstable isomers are provided herein. Cis and trans geometric isomers ofthe compounds are also included within the present embodiments and canbe isolated as a mixture of isomers or as separated isomeric forms.Where a compound capable of stereoisomerism or geometric isomerism isdesignated in its structure or name without reference to specific R/S orcis/trans configurations, it is intended that all such isomers arecontemplated.

In some embodiments, the composition comprises a compound, or apharmaceutically acceptable salt thereof, that is at least 90%, at least95%, at least 98%, or at least 99%, or 100% enantiomeric pure, whichmeans that the ratio of one enantiomer to the other in the compositionis at least 90:1 at least 95:1, at least 98:1, or at least 99:1, or iscompletely in the form of one enantiomer over the other.

Resolution of racemic mixtures of compounds can be carried out by any ofnumerous methods known in the art, including, for example, chiral HPLC,fractional recrystallization using a chiral resolving acid which is anoptically active, salt-forming organic acid. Suitable resolving agentsfor fractional recrystallization methods include, but are not limitedto, optically active acids, such as the D and L forms of tartaric acid,diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malicacid, lactic acid, and the various optically active camphorsulfonicacids such as β-camphorsulfonic acid. Other resolving agents suitablefor fractional crystallization methods include, but are not limited to,stereoisomerically pure forms of α-methylbenzylamine (e.g., S and Rforms, or diastereomerically pure forms), 2-phenylglycinol,norephedrine, ephedrine, N-methylephedrine, cyclohexylethylamine,1,2-diaminocyclohexane, and the like. Resolution of racemic mixtures canalso be carried out by elution on a column packed with an opticallyactive resolving agent (e.g., dinitrobenzoylphenylglycine). Suitableelution solvent compositions can be determined by one skilled in theart.

Compounds may also include tautomeric forms. Tautomeric forms resultfrom the swapping of a single bond with an adjacent double bond togetherwith the concomitant migration of a proton. Tautomeric forms includeprototropic tautomers which are isomeric protonation states having thesame empirical formula and total charge. Examples of prototropictautomers include, but are not limited to, ketone-enol pairs,amide-imidic acid pairs, lactam-lactim pairs, amide-imidic acid pairs,enamine-imine pairs, and annular forms where a proton can occupy two ormore positions of a heterocyclic system including, but not limited to,1H- and 3H-imidazole, 1H-, 2H- and 4H-1,2,4-triazole, 1H- and2H-isoindole, and 1H- and 2H-pyrazole. Tautomeric forms can be inequilibrium or sterically locked into one form by appropriatesubstitution.

Compounds also include hydrates and solvates, as well as anhydrous andnon-solvated forms.

Compounds can also include all isotopes of atoms occurring in theintermediates or final compounds. Isotopes include those atoms havingthe same atomic number but different mass numbers. For example, isotopesof hydrogen include tritium and deuterium.

In some embodiments, the compounds, or salts thereof, are substantiallyisolated. Partial separation can include, for example, a compositionenriched in the compound. Substantial separation can includecompositions containing at least about 50%, at least about 60%, at leastabout 70%, at least about 80%, at least about 90%, at least about 95%,at least about 97%, or at least about 99% by weight of the compound, orsalt thereof. Methods for isolating compounds and their salts areroutine in the art.

Although the disclosed compounds are suitable, other functional groupscan be incorporated into the compound with an expectation of similarresults. In particular, thioamides and thioesters are anticipated tohave very similar properties. The distance between aromatic rings canimpact the geometrical pattern of the compound and this distance can bealtered by incorporating aliphatic chains of varying length, which canbe optionally substituted or can comprise an amino acid, a dicarboxylicacid or a diamine. The distance between and the relative orientation ofmonomers within the compounds can also be altered by replacing the amidebond with a surrogate having additional atoms. Thus, replacing acarbonyl group with a dicarbonyl alters the distance between themonomers and the propensity of dicarbonyl unit to adopt ananti-arrangement of the two carbonyl moiety and alter the periodicity ofthe compound. Pyromellitic anhydride represents still anotheralternative to simple amide linkages which can alter the conformationand physical properties of the compound. Modern methods of solid phaseorganic chemistry (E. Atherton and R. C. Sheppard, Solid Phase PeptideSynthesis A Practical Approach IRL Press Oxford 1989) now allow thesynthesis of homodisperse compounds with molecular weights approaching5,000 Daltons. Other substitution patterns are equally effective.

The compounds also include derivatives referred to as prodrugs.

Compounds containing an amine function can also form N-oxides. Areference herein to a compound that contains an amine function alsoincludes the N-oxide. Where a compound contains several amine functions,one or more than one nitrogen atom can be oxidized to form an N-oxide.

Examples of N-oxides include N-oxides of a tertiary amine or a nitrogenatom of a nitrogen-containing heterocycle. N-Oxides can be formed bytreatment of the corresponding amine with an oxidizing agent such ashydrogen peroxide or a per-acid (e.g., a peroxycarboxylic acid) (see,Advanced Organic Chemistry, by Jerry March, 4th Edition, WileyInterscience).

Embodiments of various compounds and salts thereof are provided. Where avariable is not specifically recited, the variable can be any optiondescribed herein, except as otherwise noted or dictated by context.

In someembodiments, the subject is a subject in need of such treatment. Asdescribed herein, in some embodiments, the subject is a mammal, such as,but not limited to, a human.

In some embodiments, also provided are one or more compounds describedabove, or a pharmaceutically acceptable salt thereof, or apharmaceutical composition comprising one or more compounds describedabove, for use in the manufacture of a medicament for the treatment ofmethods of treating and/or preventing pain, including, but not limitedto the conditions described herein, in a subject, such as thosedescribed herein. In some embodiments, the subject is a subject in needthereof.

The present embodiments also provides the use of one or more compoundsdescribed above, or a pharmaceutically acceptable salt thereof, or apharmaceutical composition comprising one or more compounds describedabove, in the modulation of a S₁P₁ receptor activity, such as thepresence on the surface of the cell. In some embodiments, the compounds,pharmaceutically acceptable salt thereof, or a pharmaceuticalcomposition of the same modulate the internalization, trafficking,and/or degradation of the S₁P₁ receptor. In some embodiments, thecompounds, pharmaceutically acceptable salt thereof, or a pharmaceuticalcomposition of the same modulate the G-protein modulated pathway of theS₁P₁ receptor.

As used herein, “modulation” can refer to either inhibition orenhancement of a specific activity. For example, the modulation of theS₁P₁ receptor can refer to the inhibition and/or activation of theG-protein mediated pathway of the S₁P₁ receptor. In some embodiments,the modulation refers to the inhibition or activation of the β-arrestinmediated pathway of the S₁P₁ receptor. In some embodiments, themodulation refers to the inhibition or activation of the internalizationof the S₁P₁ receptor. The activity of a S₁P₁ receptor can be measured byany method including but not limited to the methods described herein.

The compounds described herien are agonists or antagonists of the S₁P₁receptor. The ability of the compounds to stimulate or inhibit S₁P₁receptor signaling may be measured using any assay known in the art usedto detect S₁P₁ receptor mediated signaling or S₁P₁ receptor activity, orthe absence of such signaling/activity. “S₁P₁ receptor activity” refersto the ability of a S₁P₁ receptor to transduce a signal. Such activitycan be measured, e.g., in a heterologous cell, by coupling an S₁P₁receptor (or a chimeric S₁P₁ receptor) to a downstream effector such asadenylate cyclase.

A “natural ligand-induced activity” as used herein, refers to activationof the S₁P₁ receptor by a natural ligand of the S₁P₁ receptor. Activitycan be assessed using any number of endpoints to measure S₁P₁ receptoractivity.

Generally, assays for testing compounds that modulate S₁P₁receptor-mediated signal transduction include the determination of anyparameter that is indirectly or directly under the influence of a S₁P₁receptor, e.g., a functional, physical, or chemical effect.

Samples or assays comprising S₁P₁ receptors that are treated with apotential activator, inhibitor, or modulator are compared to controlsamples without the inhibitor, activator, or modulator to examine theextent of inhibition. Control samples (untreated with inhibitors) areassigned a relative S₁P₁ receptor activity value of 100%. Inhibition ofa S₁P₁ receptor is achieved when the S₁P₁ receptor activity valuerelative to the control is about 80%, 50%, or 25%. Activation of a S₁P₁receptor is achieved when the S₁P₁ receptor activity value relative tothe control (untreated with activators) is 110%, 150%, or 200-500%(i.e., two to five fold higher relative to the control), or 1000-3000%or higher.

The effects of the compounds upon the function of an S₁P₁ receptor canbe measured by examining any of the parameters described above. Anysuitable physiological change that affects S₁P₁ receptor activity can beused to assess the influence of a compound on the S₁P₁ receptors andnatural ligand-mediated S₁P₁ receptor activity. When the functionalconsequences are determined using intact cells or animals, one can alsomeasure a variety of effects such as changes in intracellular secondmessengers such as cAMP.

Modulators of S₁P₁ receptor activity can be tested using S₁P₁ receptorpolypeptides as described herein, either recombinant or naturallyoccurring. The protein can be isolated, expressed in a cell, expressedin a membrane derived from a cell, expressed in tissue or in an animal.For example, neuronal cells, cells of the immune system, transformedcells, or membranes can be used to test the S₁P₁ receptor polypeptidesdescribed herein. Modulation is tested using one of the in vitro or invivo assays described herein. Signal transduction and cellulartrafficking can also be examined in vitro with soluble or solid statereactions, using a chimeric molecule such as an extracellular domain ofa receptor covalently linked to a heterologous signal transductiondomain, or a heterologous extracellular domain covalently linked to thetransmembrane and or cytoplasmic domain of a receptor. Furthermore,ligand-binding domains of the protein of interest can be used in vitroin soluble or solid state reactions to assay for ligand binding.

Ligand binding to an S₁P₁ receptor, a domain, or chimeric protein can betested in a number of formats. Binding can be performed in solution, ina bilayer membrane, attached to a solid phase, in a lipid monolayer, orin vesicles. For example, in an assay, the binding of the natural ligandto its receptor is measured in the presence of a candidate modulator,such as the compound described herein. Alternatively, the binding of thecandidate modulator may be measured in the presence of the naturalligand. Often, competitive assays that measure the ability of a compoundto compete with binding of the natural ligand to the receptor are used.Binding can be tested by measuring, e.g., changes in spectroscopiccharacteristics (e.g., fluorescence, absorbance, refractive index),hydrodynamic (e.g., shape) changes, or changes in chromatographic orsolubility properties.

Another technology that can be used to evaluate S₁P₁ receptor-proteininteractions in living cells involves bioluminescence resonance energytransfer (BRET). A detailed discussion regarding BRET can be found inKroeger et al., J. Biol. Chem., 276(16):12736 43 (2001).

After the receptor is expressed in a cell the cells can be grown inappropriate media in the appropriate cell plate. The cells can beplated, for example at 5000-10000 cells per well in a 384 well plate. Insome embodiments, the cells are plated at about 1000, 2000, 3000, 4000,5000, 6000, 7000, 8000, 9000, or 10000 cells/per well. The plates canhave any number of wells and the number of cells can be modifiedaccordingly.

Example 3: S₁P₁ Receptor are Effective to Treat Chemotherapeutic InducedPeripheral Neuropathy

Compounds were tested for efficacy in mouse models of chemotherapyinduced peripheral neuropathy. The intraperitoneal (i.p.) injection ofchemotherapeutics in rodents has been shown to induce sensory impairmentand pain, similar to what is seen in humans where these sensations beginwithin days and last for several weeks. For these studies c57bl/6 miceare habituated to the test environment and baseline measurements of painsensitivity are assessed. To determine mechanical responses, thethreshold for responses to punctate mechanical stimuli (mechanicalhyperalgesia) was tested according to the frequency method. In brief,the plantar surface of the animal hindpaw was stimulated with a singlevon Frey monofilament (0.4 g) for approximately 1-2 seconds. If therewas a withdrawal response, it was recorded as a positive response. Aresponse was defined as a lifting or shaking of the paw uponstimulation. This was repeated ten times for each mouse. The finalmeasurement for each mouse is the % non-response to stimulation for theten trials. The % non-response to stimulation is converted to a % MPE.For paclitaxel induced peripheral neuropathy, a series of injections ofPAC (6 mg/kg, i.p.) on days 1, 3, 5 and 7 is used to induce peripheralneuropathy. After approximately 14 days from the initiation of PACinjections, animals are re-assessed for mechanical sensitivity. Animalsthat exhibit a 50% response rate and lower can be included in studieswith test compounds. On test day animals are dosed with compounds eithersubcutaneously or orally and tested for mechanical response by thefrequency method either 30 min (s.c.) or 60 min (p.o.) after drugadministration. Data is presented as a % MPE. For oxaliplatin inducedperipheral neuropathy, a series of injections of OXA (4 mg/kg, i.p.) ondays 1-5 is used to induce peripheral neuropathy. After approximately 14days from the initiation of PAC injections, animals are re-assessed formechanical sensitivity. Animals that exhibit a 50% response rate andlower can be included in studies with test compounds. On test dayanimals are dosed with compounds subcutaneously and tested formechanical response by the frequency method 30 min after drugadministration. Data is presented as a % MPE. One or more of thecompounds show reversal of chemotherapeutic induced peripheralneuropathy.

A compound was tested for the ability to prevent the development of OXAinduced peripheral neuropathy. A concurrent with the OXA injections onDay 1-5, a compound was dosed (3 mg/kg, sc) every day for 15 days. OnDay 16 animals were tested for mechanical allodynia. Animals treatedwith a test compound did not exhibit peripheral neuropathy. The data forexemplary compounds is provided below.

Example 4: The S₁P₁ Receptor Compounds can be Used to Treat Inflammationand Pain

Assessment of Tactile Allodynia Produced by Intraplantar Freund'sComplete Adjuvant in Rats:

Animals were acclimated to the vivarium for at least 48 hr prior tobehavioral testing. Inflammation was induced with the administration ofan intraplantar (subcutaneous injection into the plantar surface of thehind paw, i.pl.) injection of 0.10 ml Freund's Complete Adjuvant (FCA).

The experiments were conducted 24 hours after CFA administration. Ratsare tested for mechanical allodynia in a Randall-Selitto apparatus. Theinflamed paw is put on a pedestal and a pointed force of increasingintensity (0 to 250 grams) is applied to the paw. When the animalstruggles to withdraw from the force the test is stopped and the forceto induce that struggle is recorded. Data is presented as mean grams offorce to withdrawal or a percentage of the maximum possible effect.

Example 6: The S₁P₁ Receptor Compounds can be Used to Treat DiabeticNeuropathy

Assessment of Tactile Allodynia and Thermal Hyperalgesia in a RodentModel of Diabetic Neuropathy—Streptozotocin-Induced (STZ)

A cohort of 48 male Sprague Dawley rats, weighing 225-250 g at arrival,was group housed under constant temperature, humidity and a 12-hourlight-dark cycle. Following acclimation to the animal colony, theanimals were tested for baseline withdrawal responses to mechanicalallodynia and thermal hyperalgesia using the methods described below inChaplan, S. R., Bach, F. W., Pogrel, J. W., Chung, J. M. and Yaksh, T.L. Quantitative assessment of tactile allodynia in the rat paw. J.Neurosci. Methods 53: 55-63, 1994; Joris, J.

Animal Models ofPainful Diabetic Neuropathy: The STZ rat model. Current Protocols inNeuroscience, November; Chapter 9, Unit 9.18, 2004.

A diabetic-like state was induced with a single intraperitoneal (IP)injection of streptozotocin STZ (50 mg/kg) freshly dissolved in 10 mMcitric acid buffer was injected intraperitoneally (IP) on Day 1. Twodays later (on Day 3), hyperglycermia was confirmed by existence ofblood glucose >350 mg/dL as measured by glucometer, and the animalhealth was monitored biweekly for 12 days.

For measures of mechanical allodynia, rats were preselected forexperimentation only if the pain threshold 7-14 days after STZ injection(pre-treatment) was reduced by 10 grams of force relative to theresponse of the individual paw before STZ challenge (pre-induction),namely, with clear presence of allodynia. The rats were randomized basedon pre-dose mechanical allodynia scores to balanced treatment groups.The animals were tested prior to study inclusion for mechanicalallodynia by the manual von Frey test on Day 20 (Chaplan up/down methodusing von Frey filaments on the plantar surface of the paw). The manualvon Frey test was repeated at 0.5 or 1 hr following administrations oftest articles, vehicle, and reference compound via the specifiedroute(s) and on Day 21 post-surgery.

For measures of thermal hyperalgesia, rats were pre-selected forexperimentation only if the pain threshold 7-14 days after STZ injection(pre-treatment) was reduced by 75% relative to the response of theindividual paw before STZ challenge (pre-induction), namely, with clearpresence of hyperalgesia. The rats were randomized based on pre-dosethermal hyperalgesia scores to balanced treatment groups. Rats werepreselected (with clear presence of thermal hyperalgesia) on Day 20.Thermal hyperalgesia was measured at 1 or 1.5 hr after dosing of testarticles, vehicle, and reference compound via the specified route(s) onDay 21. Each rat was placed within a plastic box atop a glass floor for20 to 30 minutes. A light beam under the floor was aimed at the plantarsurface of the left hind paw. The time was measured automatically whenthe paw was withdrawn away from the thermal stimulus. A cut-off latencyof 23 sec was imposed. The latency to withdrawal was obtained for eachrat and defined as the heat pain threshold.

Mean thresholds and withdrawal latencies were analyzed via Two Way ANOVAfollowed by Dunnett's Multiple Comparison tests to STZ+VEH group withdifferences considered significant at p<0.05.

Exemplary compounds, but not limited to these, that were effective inthis animal model are described below. For example, compounds 103 and293 were tested and found to have active doses between 50 and 100 mg/kgin both mechanical allodynia and thermal hyperalgesia.

H. and Chung, J. M. Anexperimental model of peripheral neuropathy produced by segmental spinalnerve ligation in the rat. Pain 50: 335-63, 1992.

Animals (n=40) were anesthetized with an intraperitoneal (IP) injectionof Pentobarbital (50 mg/kg). Spinal nerve ligation (SNL) was performedby first separating the left paraspinal muscles from the spinousprocesses (L4-S2). The L6-S1 facet joint was nipped. The transverseprocess of L6 was removed to identify the locations of the L5 and L6spinal nerve. The left L5 and L6 spinal nerves were isolated and tightlyligated with 6.0 silk sutures. Another 8 animals were underwent shamsurgery only (anesthesia, surgical opening and skin suture).

For measures of mechanical allodynia, rats were preselected forexperimentation only if the pain threshold 7-14 days after SNL surgery(pre-treatment) was reduced by 10 grams of force relative to theresponse of the individual paw before surgery (pre-induction), namely,with clear presence of allodynia. The rats were randomized based onpre-dose mechanical allodynia scores to balanced treatment groups. Theanimals were tested prior to study inclusion for mechanical allodynia bythe manual von Frey test on Day 20 (Chaplan up/down method using vonFrey filaments on the plantar surface of the paw). The manual von Freytest was repeated at 0.5 or 1 hr following administrations of testarticles, vehicle, and reference compound via the specified route(s) andon Day 21 post-surgery.

Example 9: Compounds do not Cause Lymphopenia

Compounds were tested for changes in peripheral blood lymphocytes inc57bl/6 mice. In acute studies, animals (n=5/group) were dosedsubcutaneously with test compound at a dose of 3 mg/kg. Animals weresacrificed at specific time points and 500 μl of whole blood wascollected in EDTA (K2) Eppendorf tubes. Blood was stored on ice andshipped immediately overnight delivery to Charles River Laboratories foranalysis. CRL ran samples through their WBC/differential panel on anAdvia 120 instrument. We received peripheral lymphocyte counts (10³cells/μl) for each blood sample. Treatment group means were compared toa vehicle treatment group for statistical significance. In chronicstudies, animals (n=6-8/group) were dosed subcutaneously with testcompound either in a dose response paradigm (highest dose of 3 mg/kg) orin a screening paradigm at 6 mg/kg for seven days. On the seventh day,animals were sacrificed 45 minutes after the final dose. Whole blood wascollected and analyzed as described for acute studies.

Example 10: Compounds Inhibit Tumor Growth and Prolong Survival in TumorModel

Female athymic nude mice (Crl:NU(NCr)-Foxnlnu, Charles RiverLaboratories) were implanted with A2780 human ovarian carcinoma cells toinitiate tumor growth.

Each mouse received 1×107 cells (0.1 mL cell suspension) subcutaneouslyin the right flank, and tumors were monitored as their volumesapproached the target range of 100 to 150 mm₃. Fourteen days later,designated as Day 1 of the study, mice were sorted into six groups often each. The individual tumor volumes ranged from 108 to 196 mm₃ andgroup mean tumor volumes were 148 mm₃. Tumors were measured twice weeklyfor the study duration.

Paclitaxel dosing solutions were prepared in 5% ethanol, 5% Cremophor ELin D₅W (Vehicle 1). Ozanimod and Compound 103 dosing solutions wereprepared in 10% dimethylacetamide, 10% Cremophor EL, 80% sterile waterwith 10% β-cyclodextrin (Vehicle 2). Starting on Day 1 of the study, sixgroups (n=10) of female athymic nude mice with established A₂₇₈₀ tumorswere treated according to the following plan. Treatments wereadministered either by intravenous injection (i.v.) or oral gavage(p.o.) and were adjusted to the body weight of the individual animal.Group 1 received Vehicle 1, i.v., once every other day for five doses(qod×5) and Vehicle 2, p.o., once daily to the end of the study (qd toend), and served as the control group for efficacy analysis. Group 2,the paclitaxel monotherapy group, received paclitaxel i.v., qod×5 plusVehicle 2, p.o., qd to end. Group 3, the ozanimod monotherapy group,received ozanimod p.o., qd to end plus Vehicle 1, i.v., qod×5.Combination Group 4 received ozanimod p.o., qd to end plus paclitaxeli.v., qod×5. Group 5, the Compound 103 monotherapy group, receivedCompound 103 p.o., qd to end plus Vehicle 1, i.v., qod×5. CombinationGroup 6 received Compound 103 p.o., qd to end plus paclitaxel i.v.,qod×5.

Animals were monitored individually, and each mouse was euthanized whenits tumor reached the endpoint volume of 2000 mm3 or on the final day,whichever came first. The time to endpoint (TTE) was calculated for eachmouse. Treatment outcome was determined from percent tumor growth delay(% TGD), defined as the percent increase in median TTE for treatedversus control mice, with differences in TTE values between groupsdeemed statistically significant at P<0.05 using logrank survivalanalysis. Mice were also monitored for complete regression (CR) andpartial regression (PR) responses. An animal with a CR at the end of thestudy was additionally classified as a tumor-free survivor (TFS).Treatment tolerability was assessed by body weight measurements andfrequent observation for clinical signs of treatment-related sideeffects.

All regimens were acceptably-tolerated based. Control tumors exhibitedprogressive growth, attaining the 2000 mm3 endpoint in a median 9.8days, establishing a maximum possible TGD of 50.2 days (512%) for the60-day study. Paclitaxel as monotherapy provided significant (P≤0.001)survival benefit (128% TGD) compared to controls, whereas the ozanimodand Compound 103 monotherapy regimens were associated withnon-significant (P>0.05) TGD of 31% and 15%, respectively, compared withthe control. One animal receiving Compound 103 monotherapy survived thestudy with a sub-endpoint tumor. The combination of paclitaxel andozanimod was associated with 185% TGD, providing statisticallysignificant survival benefit over either of the correspondingmonotherapies, and one study survivor with a CR/TFS tumor regressionresponse. The combination of paclitaxel and Compound 103 provided 193%TGD, a significant result compared with paclitaxel monotherapy, but notstatistically different (P>0.05) from the result for ozanimodmonotherapy.

SUMMARY

The present example evaluated test agents ozanimod and Compound 103 eachin combination with paclitaxel for efficacy in the A2780 human ovariancarcinoma model in female athymic mice. All regimens wereacceptably-tolerated. Control tumors exhibited progressive growth,attaining the 2000 mm3 endpoint in a median 9.8 days, establishing amaximum possible TGD of 50.2 days (512%) for the 60-day study.Paclitaxel as monotherapy provided significant (P≤0.05) survival benefit(128% TGD) compared to controls, whereas the ozanimod and Compound 103monotherapy regimens were associated with non-significant (P>0.05) TGDof 31% and 15%, respectively, compared with the control. One animalreceiving Compound 103 monotherapy survived the study with asub-endpoint tumor. The combination of paclitaxel and ozanimod wasassociated with 185% TGD, providing statistically significant survivalbenefit over either of the corresponding monotherapies, and one studysurvivor with a CR/TFS tumor regression response. The combination ofpaclitaxel and Compound 103 provided 193% TGD, a significant resultcompared with paclitaxel monotherapy and more than additive as comparedwith the corresponding monotherapies.
